METHOD OF MANUFACTURING GAS.

To ollwhom it may concern.:

Be itknown tha-til, HENRY M'. PInRsoN, a citizen-of the United States, residing at the the county of Kings, city and State of eiv York. have. invented an Improvement in the Method of Manufacturing Gas, of which the. following is a speci'- fic-ation.

My invention relates to a method of manufacturing luminous Water gas. In other words, illuminating gas for lighting purposes by which its economical and rapid production is made possible and by which atfthe saine time a fuel is produced that is ai-'ailable in its manufacture.

-llly limproved method consists generic ally in forcing air int-o and heating a body of fuel and making therein producer gas, passing the heated producer gas through a body of bituminous coal -and therebyT extracting chemical substances therefrom and so produc-ing of the bituminous coal a. fuel colte, conveying aivay the gases so formed and burning the saine and so bringing to a high heat the interior of a suitable apparatus or carburetor, in which the said gas is to be fixed, then closing vofi' the supply of air at both thev generator end at the place where the reducer gas is burned by the further intro(Y uction of air, then introducing lsteam under pressure into the body ofincandesc-ent fuelV and decomposing the saine into its coniponent arts and forming Water gas, simultaneous y 'ntroducing hydro-carbon of suitable consistency into the body of coke and bituminous coal and vaporizing the saine, vpassing the Water gas on through the body of coke and bituminous coal and enriching` the same by taking- -up such substances as ole'- fines andcarrying the same through the aforesaid heatedch-(nnber where the gas is fixed; thereafter conveying the gas to a suitable holder for use as an illu minant and thereafter adding` the fuel colte produced from the bituminous coal to the body of fuel .-the temperature of which has been greatly reduced by making the Water gas-for replenishing the same and progressively repeatiilg the process described AIn thedrawing l have represented. by a vertical section an apparatus adapted for carrying out the method of my invention. In this drawing the generator is shown composed of Aa shell a of suitable metall, a lingrate-bars Specification of Letters Patent.

l) and with an air-inlet pipe 721, pipe c and'preferably With stoke-holes d di having removable covers. A vertically disposed retort enters the top of the generator; said retort essentially comprising the shell parts of metal e el between which are secured the support rings 5 6' 7 and Within these are hl h2 formed With iianges 2 3 .l, resting the one on the other and tapering from one end to the other, the lower end of the larger chamber extending down into the retort and said retort chambers supported at their flanges upon the support rings 5 6 7, said structurebeing firmly supported upon the eye-beams f and the cross support beams g.. At the upper end of the retort there is a hopper i connected by preference to a beam S and formed at its lower end with a drum i Within which is a revoluble feeder l'. i

The hopper is to be sup lied with bituminous coal and the same is ed by the feeder 7c into the smaller end of the retortfalling through the retort and filling up the saine; the said bituminous coal or coke resting upon the fuel in the generator at all times. l provide a carburetor Z of Well-lrnown construction which is shown resting upon a suitable ,foundation Z1. This carbureter is provided ivith a shell, a refractory material lining anda is connected by the throat m to the upper and higher end of the retort. An

a steam inlet air-pipe vn opens Within the throat fmand ipes o for oil or suitable liydro-carbon are introduced into the retort. Gras conduits or pipes 'l' r1 extend from the loiver end of the carlni-reter and the carbureter is preferably filled with checker-brick, or equivalent broken particles. 1 is. provided with a valve t to close off t 1e saine and resting above this pipe. is a smokeveying away t ie illuminating gas to a suitable gasoineter or holder.

ln the method of manufacturing luminous or illuminating gas with this apparatus` the fuel in the generator is firs-t fired-by the in troduction of air from the pipe b* under pressure and'is blown up to -incandescence and producer gas made: the said producer gas passing on through the bituminous coal and extracting therefrom some of the chemical substances. As the enriched produc-er gas enters the throat- 47n it is 'met by an iii-coming supply of'air from the pipe n. and is then -stach the pipe 1-1 being employed for con- 'lf he upper end of the pi e burned so that perfect combustion is produced by the abundant supply of air.- The 4heated gases then pass on through the throat into the carbureter heating up the checkerbrick Atherein to the desired and Visually determined condition or degree of heat. In the meantime however, and with the starting of the apparatus, the valve t has been lifted off the end of the pipe r and the products of the perfect combustion pass up the stack s. When the fuel in the enerator and the checker-brick in the car ureter have been brought to a proper degree of heat or .The steam as it is forced through the hetv body of xfuel'in the generator is decomposed and resolved into its constituent elementsl forming water gas and it passes on through the coke and the bituminous coal now in a hot condition in the retort to complete the taking up therefrom of the chemical substances and so produce of the bituminous coal a fuel coke and at the same time taking up thevapors of the hydro-carbon liquid and beconung enriched thereby.

y erator.

The enriched water gas non' passes on .through the throat m into the carbureter Z, passing through the interstices of the hot clieckenbricl where the gases are thoroughly mixed and converted into fixed luminous or illunfiinating gas. The gas so produced is conveyed away by the pipe r1 into suitable generator or holder for future use. The temperature of the fuel in the generator is reduced, by thus making the gas, to such a point that it requiresboth replei'iishing and building up, the ashes are removed a nd the mass of fuel settles, the coke in the retort progressively descending or fall-- ing down from the retort onto the bed of fuel as additional fuel for replenishing the gen The. retort is then filled up from the hopper 'i by the feeder 7c with fresh bituminous coal and the operations as hercinbefore described are similarly progressively repeated.

In the manufacture of luminous or illuint nating gas as hereinbefore described', the first product of blowing up the generator is producer gas, and the apparatus herein described utilizes and burns the same; or in other Words, consumes it for the purpose of heating u the carbureter necessary and useful 1n tlie production of luminous or illuminating gas which follows In the method hereinbefore described by me, and because the generator and the retort opening therefrom and forming a continua tion thereof produce an elongated lire chamber of hot fuel, the steam uudecoinposed in the fire of the generator is fully decomposed in the upper chambered end of the generator and in the ilre of the retort, and considerable carbonio acid 0.0.2 which in the manufacture of gas does escape in a shallow fire, is in my a paratus and lprocess recouvert-ed into 0.0. oy the extra e ement of oxygen of the 0.0.2 taking up an element of carbon in the retort and forming an additional volume of 0.0., thus doubling the volume of this gas made and greatly increasing the heat units of the same.
